JOBLESS RATE UP

Florida's unemployment rate edged up three-tenths of a percentage point in March to 6.4 percent. Declining: The number of manufacturing, construction and agricultural jobs. Reason: Rebecca Rust, a Florida Labor Department analyst, said the number of unemployed statewide rose in large part because of the January freeze that shortened the citrus harvest. Those with jobs: Down by 2,000 last month to 4,997,000, but still 198,000 more employed than in March 1984, when the jobless rate was 5.8 percent, Rust said. Increasing: Both the government and services sectors.
